I can't believe that Barcelona can beat Girona easily after what Girona has proven this season. Girona must be considered one of the best teams in La Liga with their achievements in the last 15 matches, so no one can underestimate them anymore even though Girona does not have a better squad than Barcelona. Of course, Xavi and his players know how dangerous Girona are, so they must really be able to do a great job against a team that has only lost 1 defeat in the last 15 matches so far.
Barcelona will face several former players in the match against Girona, especially Eric Garcia and Pablo Torre. Both have been important players in Girona's squad this season and Garcia is an irreplaceable player in defence. Eric Garcia's performance was really good at Girona, he had a fantastic loan spell at Girona and that also happened to Pablo Torre.
However, statistically in their 5 meetings, of course Barcelona can easily beat Girona and even 3-1. I think that in the upcoming match, Barcelona will be favored enough to win this match because they are playing at home and of course their confidence will be strong enough to be able to overthrow Girona. Even though Girona appeared consistent until Week 15, this match will be quite difficult for them because Barcelona is a team that is quite difficult for them to beat.
Moreover, Barcelona wants to catch up on points from Girona and Real Madrid, so Xavi will advise his team to play better so as not to lose points in this match. One of the best achievements made by Girona is maintaining their quality quite well so far but their strength will be tested by Barcelona next week. So if Girona loses then they will not have another chance to disturb Real Madrid at the top of the standings. Lewandowksi has recently had difficulty scoring goals and maybe he will try hard to find his best form when facing Girona.
